Computer-supported monitoring of an energy consumption of a means of transportation

Abstract

A method and arrangement are configured for determination of the energy consumption of a transportation device per section of the route, in urban traffic, for example. In an embodiment, current energy consumption data is compared to reference data from a fleet of transportation devices. The result is visually conveyed to the driver to allow them an interpretation of the energy consumption and to provide motivation for energy-saving driving behavior. An evaluation of the energy consumption data relative to the route allows specific feedback, for example, that the driver has achieved an energy-saving best value for a section of the route. The gathered data can also be used to pay bonuses or to initiate training measures.

 retrieving comparison data from a database, the comparison data specifying an energy consumption of transportation devices on previous journeys on the given route; and 
 comparing the energy consumption data with the comparison data to form energy consumption information and outputting the energy consumption information through an output to an operator of the transportation device. 
 
     
     
       2. The method according to  claim 1 , which comprises maintaining the database in a data memory on the transportation device. 
     
     
       3. The method according to  claim 1 , which comprises maintaining the database in a data memory external to the transportation device. 
     
     
       4. The method according to  claim 1 , wherein the output is a visual output device. 
     
     
       5. The method according to  claim 1 , wherein the transportation device is a rail vehicle, a public bus, a truck, a ferry, or an aircraft. 
     
     
       6. The method according to  claim 1 , which comprises comparing the energy consumption data only with comparison data specifying an energy consumption of transport devices
 on previous journeys of the driver; 
 on previous journeys during a predetermined period; or 
 on previous journeys with a transportation device with the same loading. 
 
     
     
       7. The method according to  claim 1 , which comprises carrying out the method iteratively for consecutive routes, and thereby:
 forming overall energy consumption data from a sum of the energy consumption data determined for the consecutive routes, which specifies an energy consumption of the transportation device on main overall route which is made up of the consecutive routes; 
 forming overall comparison data from a sum of the comparison data determined for the consecutive routes, which specifies an energy consumption of transportation devices on previous journeys on the overall route; and 
 outputting overall energy consumption information formed from a comparison of the overall energy consumption data with the overall comparison data to the operator of the transportation device. 
 
     
     
       8. The method according to  claim 1 , which comprises:
 determining assistance data consisting of
 cooperation data specifying whether or with what delay the operator has followed instructions of an operator assistance system on the route; or 
 acceleration data specifying braking and acceleration processes on the route; 
 
 acquiring comparison assistance data from the database, the comparison assistance data specifying cooperation data or acceleration data of transportation devices on previous journeys on the route; and 
 outputting assistance information formed from a comparison of the assistance data with the comparison assistance data via an output device to the operator of the transportation device. 
 
     
     
       9. The method according to  claim 1 , which comprises writing the energy consumption data into the database for use as comparison data in future journeys. 
     
     
       10. A computer-readable data carrier having a computer program stored thereon in non-transitory form, the computer program executing the method according to  claim 1  when it is loaded into and processed in a processing unit. 
     
     
       11. A computer program stored on a non-transitory computer readable medium and configured for processing in a processing unit and, on processing, executing the method according to  claim 1 . 
     
     
       12. A system for computer-supported monitoring of an energy consumption of a transportation device, the system comprising:
 an interface configured for receiving measurement data from a least one measurement device, the measurement data specifying a current energy consumption of the transportation device; 
 a processing unit programmed for determining energy consumption data from the measurement data, the energy consumption data specifying an energy consumption of the transportation device on a route;
